Melatonin is a hormone made by a part of the brain called the pineal gland. It may help our bodies know when it’s time to go to sleep and to wake up. There are two types of melatonin that may be used in pill form: natural and synthetic (man-made). Natural melatonin is made from the pineal gland of animals. This form could be contaminated with a virus and is not recommended. The synthetic form of melatonin does not have this risk.
Melatonin is most often used to treat insomnia (difficulty falling asleep and/or staying asleep) in individuals with autism. While it may be infrequent, some people who have taken melatonin have reported sleepiness, headache, a “heavy-head” feeling, stomach discomfort, depression or feeling hungover. Further study is needed to find out more about melatonin’s side effects, especially delayed or long-term effects.
A survey of the medical literature reveals antioxidant and anti-cytokine activity of melatonin. Cytokines are a group of proteins and peptides used in organisms as signaling compounds and are involved in a variety of immunological, inflammatory and infectious diseases. Basically, melatonin helps to protect DNA from oxidant stress. Melatonin is considered by some to be an antioxidant vitamin. It is a vitamin for those who cannot make enough of it in their own bodies, which appears to be true for a majority of individuals on the autism spectrum.
